Off of Rt 45 in Temple, New Hampshire on Howard Hill Road is a little hidden gem. About a mile down the road on the left is a gated dirt road. Park anywhere along the road and walk up the road to another gate and continue up to the white ledge. There has been some logging on the first part of the road so make sure you continue straight to stay on the trail. The trail is little under a half mile one way.
Once at the top there there is a good size out cropping of white rock is such a fun place for kids to climb and explore. I have also gone up to view the moon and star gaze. There are decent review looking towards Wilton, Milford, Manchester and Nashua. This trail is good for children, families and beginner hikers.
